I got

full tank of vpower in my tubby.

im going to scrap it and want to drain the fuel.

the car is currently standing on 2 wheels from the middle so i believe the tank is not accessible.

I've been told about sucking a pipe from the petrol cap entry.

How exactly would i do this, how long should a pipe be, and what diameter? ive tried with a garden hose

(15mm?) but it doesnt go in far enough.

and what elevations should the ends of the pipe be for science to take effect correctly and raing the tank?
